RESUMO
PURPOSE: There is evidence from some studies that support an association between obesity in adults and higher intraocular pressure (IOP). However, this association has not been completely studied in children. Our aim is to evaluate the association between child body mass index (BMI) and IOP. METHODS: Ninety-six children attending the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) in Brazil were studied. Thirty-three were overweight/obese with a mean BMI of 29.7 ± 5.2 and 63 with a mean BMI of 20.8 ± 3.3. IOP was measured using the Goldmann applanation tonometer and was corrected for corneal thickness. The coefficient of correlation between BMI and IOP was calculated. RESULTS: There was no significant difference in the IOP of children with or without overweight/obesity. The mean IOP was 13.5 and 13.0 mmHg for the right eye and 13.1 and 12.9 mmHg for left eye, respectively (p=0.38 and p=0.71). The results remained the same after correction by pachymetry; 13.0 and 13.1 mmHg for the right eye and 12.4 and 12.9 mmHg for the left eye, respectively (p=0.88 and p=0.41). The coefficient of correlation between BMI and IOP was 0.070 (p=0.496). CONCLUSION: These results do not show a correlation between body mass index and IOP in children. Further studies are warranted to clarify the association between BMI and IOP in children.

OBJETIVO: Alguns estudos apontam para uma associação entre obesidade e aumento da pressão intraocular em adultos. Entretanto, essa associação ainda não foi completamente estudada em crianças. O objetivo do estudo é avaliar a associação entre o índice de massa corpórea (IMC) e a pressão intraocular em crianças. MÉTODOS: Noventa e seis crianças atendidas no Instituto de Medicina Integral Prof. Fernando Figueira (IMIP), Brasil, foram estudadas. Trinta e três apresentavam excesso de peso ou obesidade com uma média de IMC de 29,7 ± 5,2 e os outros 63 tinham uma média de IMC de 20,8 ± 3,3. A pressão intraocular foi medida por meio do tonômetro de aplanação de Goldmann, corrigida pela espessura da córnea. O coeficiente de correlação entre o IMC e a pressão intraocular foi calculado. RESULTADOS: Não foi observada diferença significativa na pressão intraocular entre as crianças com e sem excesso de peso/obesidade. A média da pressão intraocular foi de 13,5 e 13,0 mmHg no olho direito e 13,1 e 12,9 mmHg no olho esquerdo, respectivamente (p=0,38 e p=0,71). Os resultados permaneceram os mesmos após a correção pela paquimetria; 13,0 e 13,1 mmHg para o olho direito e 12,4 e 12,9 mmHg para o olho esquerdo, respectivamente (p=0,88 e p=0,41). O coeficiente de correlação entre o IMC e a pressão intraocular foi 0,070 (p=0,496). CONCLUSÃO: O índice de massa corpórea não parece apresentar correlação com a pressão intraocular em crianças. Novos estudos são necessários para esclarecer a associação entre o IMC e a pressão intraocular.
